A retrospective of our international collaboration on peracetic acid as a disinfectant for aquaculture

Peracetic acid (PAA) is a combination of acetic acid and hydrogen peroxide (with a stabilizer) that degrades rapidly. It has replaced chlorine in many industries. Uses include: sanitation in food/beverage plants, agricultural facilities, wineries/breweries, greenhouse equipment, animal housing, used to prevent bio-film formation in paper/pulp industries, wastewater treatment, commercial laundries and poultry processing.

PAA is approved as a disinfectant for the US aquaculture industry for two products: • The EPA registration (June 26, 2017) for PeroxyChem’ s VigorOx® SP-15 Antimicrobial Agent is for: 1) Sanitizing surfaces of harvesting equipment used in the aquaculture industry, and 2) Cleaning and disinfecting fish culture tanks and raceways when water is drained and fish are not present. • AquaTactics’ Aqua Des™ is approved (November 3, 2017) for: 1) In-water use in fish ponds/raceways (remove fish from pond prior to use and test for residual PAA levels prior to restocking), 2) Use on aquaculture equipment (pumps, boots, foot bath mats, net dips, waders, dive equipment, etc.), and 3) Use on fish pond equipment (water free raceways, gratings, pipes, etc).
